Definitions

  • the invention relates to vehicle jacks, lifts, and stands. More specifically, the invention is directed to a jack base having retractable wheels.
  • Vehicle jacks are ubiquitous. They are required by amateurs and professionals alike to service vehicles. Jacks are often heavy and difficult to move. Certain prior art jacks utilize wheels to try to make moving the jacks easier; however, a user is still required to support the weight of the jack while moving the jack. It would be desirable to have a jack that is easily movable from one location to another.
  • a transportable jack system in one embodiment, includes a jack disposed on a base.
  • the base includes a base plate with a plurality of wheel openings formed therein, and a biasing member disposed between a wheel and the base plate.
  • the biasing member is configured from a single piece of material consisting of a top horizontal portion, a bottom horizontal portion, and an angled middle portion disposed between the top horizontal portion and the bottom horizontal portion. The biasing member biases the base away from a ground surface when a load applied to the jack is below a predetermined threshold and deforms when the load is above the predetermined threshold, wherein the deformation allows the base plate to contact the ground surface.
  • a transportable base for a vehicle lift or jack in another embodiment, includes a base plate having at least one wheel opening formed therein, and a biasing member disposed between a wheel and the base plate and secured to the base plate via a mechanical fastener.
  • the biasing member consists of one piece of material forming a top substantially horizontal portion, a bottom substantially horizontal portion; and an angled middle portion between the top and bottom portions. The biasing member biases the base plate away from a ground surface when a load applied to the base plate is below a predetermined threshold, and deforms when the load applied to the base plate is above the predetermined threshold such that the base plate comes into contact with the ground surface.
  • a transportable base for a vehicle lift or jack comprises a base plate; a connection member coupled to the base plate, the connection member comprising a base portion and a socket; a wheel assembly and a biasing member.
  • the wheel assembly comprises a post having a shoulder; an attachment arm extending at least partially around the post; and a wheel coupled to the attachment arm.
  • the post extends through an opening in the socket, and the biasing member is disposed between the shoulder and the socket and biases the wheel away from a ground surface when a load applied to the base plate is below a predetermined threshold.
  • the biasing member compresses when the load applied to the base plate is above the predetermined threshold such that the base plate comes into contact with the ground surface.

  • the bottom portion 114 C of the biasing member 114 attaches to the base plate 112 via one or more fasteners 116 .
  • the biasing member 114 must be strong enough to support the vehicle support 110 on the base plate 112 above the ground when the vehicle support 110 is not under load.
  • the biasing member 114 must be formed of a material having sufficient flexibility to allow the wheel assemblies 118 to collapse under a load L.
  • the biasing member 114 is formed from, for example, steel, aluminum, titanium, tungsten, or alloys of steel, aluminum, titanium, or tungsten. Other materials may alternately be utilized. Regardless of the material, importantly, the biasing member 114 is formed of one piece of material. The invention greatly simplifies previous designs which are prone to breaking down due to the many different components that make up the biasing system.
  • the vehicle support 110 is removable from the base 105 and replaceable with a different vehicle support 110 .
  • the base 105 may be configured to support many different types of vehicle support 110 .
  • the vehicle support 110 may be temporarily secured to the base plate 112 to ensure that the vehicle support 110 does not slide on top of the plate 112 .
  • the jack and base system 100 is transported to the desired location by moving the system 100 along a ground surface via the wheel assemblies 118 .
  • the system 100 When the system 100 is being transported, there is no load applied to the vehicle support 110 , so the system 100 may freely move along the ground surface.
  • a load L FIG. 7
  • An equal and opposite force F is applied to the base 105 via the wheel assemblies 118 , which causes the biasing member 114 to deform or flex under the load such that the base plate 112 comes into contact with the ground surface.
  • the angle ⁇ increases until a bottom surface of the base plate 112 touches the ground surface.
  • the base plate 112 comes into contact with the ground, the base 105 is prohibited from moving along the ground.
  • the biasing members 114 again bias the wheel assemblies 118 toward the ground surface such that the jack and base system 100 is again transportable via the wheel assemblies 118 .
